Question: Help please. (1 point) An undamped spring-mass system with a mass weighing 12 lb and a spring constant of 2 Ib/in is set in motion

Help please.

(1 point) An undamped spring-mass system with a mass weighing 12 lb and a spring constant of 2 Ib/in is set in motion at t = 0 by an external force of 5 cos 5t lb. Find the position u (in feet) at any time t (in seconds). u(t) = Assume that acceleration due to gravity is 32ft/s2
